"STOP IT CHRYSALIS! I KNOW IT'S YOU!"
-Then, why our horns are touching? Hmm?
"GO AWAY! YOU... YOU..."
-You're telling me you are not liking what you are seeing right now? Are you implying that you are NOT liking your own appearance? What a shame..."
"QUIET!!!! I like how I look! I don't need magic or any spell to hide my true self like you keep doing, you damn changeling queen!
-You know why I'm hiding!
"Yes! For shame to our true form-
-FOR DEVOURING YOUR PRECIOUS AND DELICIOUS LOVE!!!!
"And why so far haven't you used this natural ability of your on me?"
-Isn't that obvious?
-You emanate no love. Not even of yourself.
-Does it mean that the princess of the night doesn't actually love herself?
-And maybe because she is afraid that her evil self could take her place again and-
Luna shot a blast of blue light straight to Chrysalis chest who flew and hit the nearly wall behind her.
"I WILL NOT BECOME NIGHTMARE MOON EVER AGAIN!!! AS LONG AS I LIVE!!!"
Chrysalis cough, her spell and appearance dissipated.
-Well... for a princess who... *cough cough* seems to have forgave herself... *cough* I felt so much guilt from you that I find this pitiful.
Luna stayed on her guard, her horn pointed at the evil queen.
"I find more pitiful your way to feed."
-And yet, I could have successfully invade Equestria. BTW, do you feel guilt for not being there for your sister when I defeated her?
Luna's horn glowed.
"Yes. This my guilt. Not your! And for this you will pay. One day."
-Ha! What stops you for taking your revenge right now?
"I will keep it for another time."
"But for this time...."
Her glow covered Chrysalis who was hold in front of a huge glass window.
-W-what are you doing?
"Simple. Getting rid of a parasite."
"I already have something for making me remember anyway. BE GONE!"
She shot a huge ray of light in her direction who hit her and defenestrated the queen, flying many miles aways. Luna walked away, in the direction of Celestia's bedroom.
"I know you are sleeping, sister, but I need to talk to you right now..."
Awesome work. Too bad you put this in your scraps files.
